What is the best estimate of plates on earths crust?

The Earth's crust is divided into several major tectonic plates, with the most widely recognized estimates totaling about 15 to 20 significant plates. These include the Pacific Plate, North American Plate, Eurasian Plate, African Plate, South American Plate, Antarctic Plate, and Indo-Australian Plate, among others. Additionally, there are numerous smaller plates and microplates that contribute to the complex dynamics of plate tectonics. The interactions of these plates shape the Earth's surface, leading to phenomena such as earthquakes, volcanic activity, and mountain formation.
